This is not just local. Corona invaded the world19As a result, the problem of plastic waste is becoming more and more serious in countries around the world..

these timesAnd In order to solve the basic problem of plastic waste, it has been found that patent applications for biodegradable plastics, which are degraded much faster by microorganisms than traditional plastics, are increasing..
